Display Post Types – Post Grid, post list and post sliders Security & Risk Analysis

The "display-post-types" plugin v3.2.7 exhibits a generally strong security posture, with no known critical vulnerabilities in its history and a robust approach to input validation and access control. The static analysis reveals that all identified AJAX handlers and REST API routes are protected by permission checks, and there are no exploitable taint flows or dangerous functions present. The plugin also demonstrates good practices regarding nonce checks and capability checks, indicating a developer focused on secure coding. However, a significant concern arises from the database queries. With 100% of SQL queries not utilizing prepared statements, there's a high risk of SQL injection vulnerabilities. This lack of prepared statements, despite having a low number of total SQL queries, represents a critical oversight that could be exploited by attackers to manipulate the database.
